# ForexCodes

> ForexCodes is the quality-assurance platform for algorithmic trading code — TradingView Pine Script v6 and MetaTrader MQL4/MQL5. We verify that trading code is CORRECT (no look-ahead bias, no repainting, sound risk wiring) — never that it is profitable. Correctness ≠ profitability. Everything is educational; we make no win-rate, profit, or performance claims, and nothing on this site is financial advice. Every recommended Pine example passes our deterministic validator before publication.

Key facts:

- 107 indicator & concept guides: exact mechanics, how to read them, honest pitfalls, and a validated Pine v6 example each.
- 133 articles on Pine Script, MetaTrader EAs, backtesting honesty (overfitting, repainting, look-ahead bias), and risk education.
- 12 Pine Script error-reference pages with verbatim error text, cause, and a validated fix.
- 36 free deterministic calculators — identical inputs always give identical outputs; no predictions, no signals, no login.
- 4 public case studies where our engine's real findings (look-ahead, repaint, dead risk inputs) are shown on common strategy patterns.
- Free tools: a deterministic Pine validator and Repaint Checker that run in the browser — code never leaves the machine.
- Paid platform: Strategy Validator (Strategy Health Score™ — code correctness only), Code Fixer, Prop Compliance Checker, English→Pine, and MetaTrader MQL4/5 tools incl. Pine↔MQL conversion both ways.
- Open source: the deterministic validation engine (MIT) plus VS Code and browser extensions — https://github.com/ForexCodes-hq

- [Open Interest](https://forexcodes.com/indicators/open-interest): The total number of derivative contracts currently outstanding — a count of open positions, which is a different thing from the volume traded.
- [Gann Fan](https://forexcodes.com/indicators/gann-fan): A fan of straight lines projected from a pivot at fixed price-per-time slopes — deterministic geometry whose meaning depends entirely on a scale you must choose.
- [Linear Regression Channel](https://forexcodes.com/indicators/linear-regression-channel): A best-fit straight line through recent price with parallel deviation bands — a legitimate statistical summary that refits, and therefore repaints, on every bar.

- [Previous Day High/Low](https://forexcodes.com/indicators/previous-day-high-low): Yesterday's completed high and low plotted as fixed intraday reference lines — and a classic test case for repaint-free coding.
- [ICT Killzones](https://forexcodes.com/indicators/ict-killzones): Fixed time-of-day windows from the ICT methodology, plotted as chart highlights — defined precisely, endorsed by evidence nowhere.
- [Seasonality Analysis](https://forexcodes.com/indicators/seasonality): A statistical study that averages historical returns by calendar slot — day of week, month of year, or hour of day — to describe recurring patterns in past data.
- [TWAP (Time-Weighted Average Price)](https://forexcodes.com/indicators/twap): The running average of price over time within a session — every bar counts equally, unlike VWAP where volume sets the weights.
